制备N－2，6－二氯苯胺的新工艺路线研究

Studies on The New Preparation of N-Phenyl-2,6-Dichloroaniline

以环己酮为起始原料经２，２，６，６－四氯环己酮制备Ｎ－苯基－２，６－二氯苯胺（双氯灭痛的中间体）的新工艺路线。工艺简单、产品质量好、＂三废＂少，可较大幅度降低成本。

The new process, by which N-phenyl 2,6-dichloronailine is prepared(an intermidiate for preparing dichlofenac sodium)from the starting material cyclonexanone through 2,2,6,6-tetrachlorocyclo-hexanone, is comparablely simple, with better quality of the product,less wastes and much lower costs.
